Executive summary Executive summary: Our horizontal orbital wrapping line for copper sheet bundles provides automated, end-to-end continuous packaging. Bundles travel on powered conveyors through the central rotating ring, which applies stretch film, paper, or combined protective materials evenly across the entire surface. The entire packaging process is controlled via an intuitive PLC and HMI panel. Because processed copper sheets, bars, and profiles are highly sensitive to surface oxidation, atmospheric tarnish, and mechanical scratching during handling, end-to-end full coverage creates a sealed protective barrier against moisture and physical damage.

Station sequence: infeed, wrap and outfeed
| Station | Main operation | Key mechanism / Feature |
|---|---|---|
| Infeed | Transports raw copper sheet bundles into the packaging line | Heavy-duty powered roller conveyor system |
| Wrapping | Wraps material continuously in a spiral as the bundle moves forward | Orbital ring with variable frequency drive (VFD) |
| Control | Manages line speed, tension, overlap, and wrapping cycles | Centralized PLC touchscreen HMI control panel |
| Cover | Completes head-to-tail full encapsulation of the bundle | Integrated automatic film feeding and cutting device |
| Outfeed | Discharges fully protected copper bundles for storage or transport | Downstream powered exit conveyor |
Why copper needs a full cover
- Tarnish. Bare copper oxidizes and darkens rapidly when exposed to ambient humidity and air pollution.
- Marks. Soft non-ferrous metal surfaces scratch easily during rough fork truck transport or steel strapping.
- Fingerprints. Bare hand contact leaves skin oils that etch into the metal face over storage cycles.
- Full cover. End-to-end orbital wrapping tightly seals both ends and body length, closing off moisture, dust, and handling damage.
Turns per bundle
Worked example (illustrative).
| Item | Value |
|---|---|
| Bundle length (illustrative) | 3,000 mm |
| Wrap width (illustrative) | 150 mm |
| Overlap (illustrative) | 50% |
| Advance per turn, 150 × 0.5 | 75 mm |
| Turns per bundle, 3,000 ÷ 75 | 40 |
Operational parameters: The orbital ring operates at rotation speeds from 30 to 60 r/min with continuous conveyor feeding speeds of 2 to 16 m/min [manufacturer rating]. Wrap material overlap rate is fully adjustable between 10% and 90% via variable frequency drives to adapt to varying shipping environments [manufacturer rating].
What we set per bundle
| Setting | Depends on | Equipment rating / Feature |
|---|---|---|
| Ring size | Bundle section | Fits bundle cross-sections within ring OD 300–1500 mm [manufacturer rating] |
| Material | Film, paper or both | Handles PE film, stretch wrap, knit belt, or VCI anti-rust paper [manufacturer rating] |
| Overlap | Storage and transport | 10%–90% adjustable overlap rate via synchronized VFD drives [manufacturer rating] |
| Conveyor | Bundle length | Configured for bundle lengths from 2,000 mm up to 8,000 mm [manufacturer rating] |
System specifications: The wrapping line runs on AC 380V / 50Hz main power (or customized voltages) with a total rating of 4.8 kW [manufacturer rating]. An automatic feeding table collects bundles, while an automated clamping, feeding, and tail-cutting unit manages paper or plastic covering according to programmed length parameters [manufacturer rating].
Selection checklist
- Bundle length, width and height.
- Bundle weight (rated capacity up to 2,500 kg per bundle [manufacturer rating]).
- Packaging material choice: PE film, stretch film, VCI anti-rust paper, or dual-layer combination.
- Material overlap percentage (10% to 90%).
- Target output capacity (bundles per hour).
- Plant layout, conveyor elevation, and line integration requirements.
Safety
- Keep clear of rotating orbital ring stations and moving mechanical components during operation.
- Perimeter safety fencing and light curtains must remain active while the line runs.
- Execute complete lock-out / tag-out (LOTO) protocols before clearing material jams or changing film rolls.
- For CE compliance and European markets, the machinery is engineered and built according to ISO 12100:2010 and EN 415-10:2014 standards.
Engineering FAQ
Q: Why wrap copper sheet bundles? A: Copper tarnishes quickly when exposed to humidity and scratches easily during transport; full coverage provides a complete physical and atmospheric barrier.
Q: How does the horizontal orbital wrapper work? A: The copper bundle advances horizontally along a powered conveyor while an orbital ring rotates around it, applying wrapping material in a continuous tight spiral.
Q: How many turns are needed per bundle? A: Total turns depend on bundle length, film width, and overlap percentage. A 3,000 mm bundle using 150 mm material at 50% overlap requires 40 spiral turns, plus extra head and tail reinforcement wraps.
Q: Can the line apply paper wrapping instead of plastic film? A: Yes. The system can run PE film, stretch film, VCI anti-rust paper, or combine paper and plastic layers in a single automated process [manufacturer rating].
Q: Is this system designed for inline integration? A: Yes. The line features integrated powered conveyors and PLC architecture, enabling inline connection with upstream bundle stacking and downstream strapping stations.
Q: Which safety and engineering standards apply? A: Standard units for CE mark territories are designed to ISO 12100 safety of machinery and EN 415-10 packaging machine safety standards.
